Description

Pad composite structure and insole and protective tool using same

Technical Field

The invention relates to a cushion body composite structure, and an insole and a protective clothing using the cushion body composite structure.

Background

In general, a hard sheet such as a wood sheet or a plastic sheet is used for an impact-resistant cushion body used for sporting goods, medical protectors and the like. However, these sheets do not have flexibility and comfort, and cannot meet the requirements of general users. However, if the cushion body is formed of a general material having flexibility and comfort in the market, mechanical strength and impact resistance cannot be simultaneously achieved. In addition, generally soft cushion materials are generally less breathable. If the cushion body material is punched in order to achieve the air permeability, the mechanical strength of the cushion body may be reduced, and the problem of insufficient air permeability may occur due to insufficient number of punched holes. In addition, the conventional cushion body in the market can not be reshaped according to the requirement of the user to fit different users.

First, please refer to fig. 1A and 1B, wherein fig. 1A is a top view of a pad body composite structure 1 according to some embodiments of the present invention, and fig. 1B is a cross-sectional view of the pad body composite structure 1. The pad-body composite structure 1 comprises a fabric layer 100 and a support layer 200, wherein the fabric layer 100 is disposed on the support layer 200. In fig. 1A, the cushion body composite structure 1 has a plurality of meshes H, so that it can have good air permeability. In some embodiments, the mesh H may have a diamond shape. Although the mat body composite structure 1 in fig. 1A is drawn to have a strip shape, the invention is not limited thereto. For example, the cushion composite structure 1 may have a sheet shape according to the requirement.

Although the pad body composite structure 1 is provided with the fabric layer 100 only on one side of the supporting layer 200 in the foregoing embodiments, the invention is not limited thereto. For example, referring to FIG. 1C, there is shown a composite pad structure 2 according to other embodiments of the present invention, wherein a fabric layer 300 may be disposed on the other side of the support layer 200. Therefore, different requirements of users on softness and comfort can be further met.

Fig. 2A is a cross-sectional view of the fabric layer 100, fig. 2B is a cross-sectional view of the support layer 200, and fig. 2C is a cross-sectional view of the fabric layer 300. In some embodiments, the fabric layer 100 includes a middle layer 102 and surface layers 101 and 103 disposed on both sides of the middle layer 102. The surface layer 101 and the surface layer 103 may have meshes (e.g., diamond-shaped meshes H), and the intermediate layer 102 may be a monofilament (mono yarn) including a polymer synthetic fiber, and formed by weaving. The surface layers 101 and 103 may have a dense mesh support therebetween to avoid excessive deformation, thereby improving the mechanical properties of the fabric layer 100 and reducing the discoloration of the fabric layer 100. In addition, the fabric layer 100 may be used to directly contact the human body to provide softness and comfort. Furthermore, in some embodiments, the fabric layer 100 may comprise a fabric material having water-proof or antibacterial properties. The fabric layer 300 may include a middle layer 302, and a surface layer 301 and a surface layer 303 disposed on both sides of the middle layer 302, and the structure and material thereof are similar to those of the fabric layer 100, and will not be described herein again.

The support layer 200 mainly comprises a support structure 202 and a surface layer 201 and a surface layer 203 arranged on both sides of the support structure 202. In some embodiments, the surface layer 201, the support structure 202, and the surface layer 203 may be formed of the same material. In some embodiments, the support structure 202 may have a mesh-like structure, and the polymer layer 204 may be coated on the surface of the support structure 202. In other words, in fig. 2B, the support layer 200 may have a plurality of holes 205, rather than completely filling the voids of the support layer 200 with the polymer layer 204, when viewed from a direction perpendicular to the normal line of the support layer 200 (when viewed from the Y direction). Accordingly, the air permeability of the support layer 200 may be increased. In some embodiments, the support structure 202 may be formed of a flexible material.

In some embodiments, the support layer 200 may also have a mesh H, and the mesh has a shrinkage ratio of 50% or less, such as 40% or less, 30% or less, or 20% or less. The shrinkage ratio is defined as the ratio of (average diameter of meshes H before forming the polymer layer 204-average diameter of meshes H after forming the polymer layer 204)/(average diameter of meshes H before forming the polymer layer 204). Therefore, the air permeability can be further improved.

In some embodiments, the material of the polymer layer 204 may include a random copolymer (random copolymer) or a block copolymer (block copolymer) of a high molecular material such as polyester (e.g., Polycaprolactone (PCL)), Polyurethane (PU), Polyamide (PA), polyol, and the like. In some embodiments, the Tm of the polymer layer 204 is less than about 70 ℃, such that the temperature of the polymer layer 204 can be increased above its Tm by low temperature heating such as microwave oven or blower, which is convenient for the average user to process the mat composite 1 by himself. In some embodiments, the Tm point of polymer layer 204 is greater than about 65 ℃ to ensure that polymer layer 204 has good mechanical properties. In some embodiments, polymer layer 204 includes a chain entangled (chain entangled) polymer material to enhance its mechanical properties as well as impact resistance. By coating the polymer layer 204 on the surface of the support structure 202, the mechanical properties of the mat body composite structure 1 as a whole may be enhanced.

In some embodiments, the polymer layer 204 can be formed by heating a polymer material to increase processability, thereby coating the polymer layer 204 on the surface of the support structure 202 (e.g., forming the polymer layer 204 by a method including thermal adhesive coating, hereinafter referred to as heating), without using a low molecular weight (e.g., Mw <1000) organic compound to reduce viscosity and mixing to form the polymer layer 204. Therefore, the low molecular weight compound can be prevented from remaining in the polymer layer 204 to enhance the mechanical properties (such as adhesion, maximum stress, hardness, etc.) of the polymer layer 204, and the residual low molecular weight compound can be prevented from being released during use, thereby avoiding the environmental problem.

Table 1 is the mechanical properties of the mat body composite structure 1 after the polymer layer 204 is formed by directly heating the high molecular material in some embodiments, and table 2 is a comparative example of the mechanical properties of the mat body composite structure after the polymer layer 204 is formed by material kneading using a low molecular compound (hereinafter, referred to as a kneading manner).

TABLE 1 Mat composite Structure 1 Using heating to form Polymer layer 204

TABLE 2 Mat composite Structure Using a kneading approach to form Polymer layer 204

Specifically, the Shore hardness (Shore Durometer, D) in the foregoing test is a hardness measured by a Shore hardness tester (Shore scleroscope) by a striking test of a material surface using a small weight in a direction perpendicular to the composite structure of the pad body. The maximum stress test is a value obtained by stretching a mat composite structure having a size of 3 cm x 10 cm at a rate of 100 mm/min. The adhesive force is controlled by combining two pad bodies with a size of 3 cm x 10 cm at 4kg/cm²After the pressure was pressed together, the ends of the two mat composite structures were left at 3 cm each for tensile testing, and the stress at tear was measured. Further, when the polymer layer 204 is not disposed on the support layer 200, the maximum stress of the fabric layer 100 and the support layer 200 is 12.09MPa at 30 ℃.

From the comparison results in tables 1 and 2, it is understood that the polymer layer 204 formed by the heating method has better mechanical properties than the polymer layer 204 formed by the kneading method. For example, the pad body composite structure 1 in Table 1 has a Shore hardness greater than 45 at 30 ℃ and less than 2 at 70 ℃, an adhesion greater than 20MPa at 30 ℃ and a maximum stress greater than 100MPa at 30 ℃. Thus, the cushion body composite structure 1 can be deformed at a high temperature (e.g., about 65 ℃ to about 70 ℃) to fix its shape at a low temperature (e.g., room temperature), and has good adhesion and impact resistance.

Tables 3 and 4 show thermal property data of the polymer layer 204 formed by the heating method and the kneading method, respectively.

TABLE 3 Polymer layer 204 formed using heating

T_m1(℃)	ΔH_m1(J/g)	T_m2(℃)	ΔH_m2(J/g)
				66.4	44.1	255.7	17.1

Note: t is_m1Is still present after multiple DSC measurements, and T_m1Value and Δ H_m1There is not much difference.

Note: at the second DSC measurement, T_m1And Δ H_m1All do not exist, represent that the crystal is not easy to be damaged

And (4) generating.

The thermal properties of the aforementioned polymer layer 204 were tested by means of Differential scanning calorimetry () Differential scanning calorimetry, DSC). Specifically, the sample was first warmed from 30 ℃ to 300 ℃ at a rate of 20 ℃/min, then maintained at a temperature of 300 ℃ for 5 minutes, and then cooled from 300 ℃ to 30 ℃ at a rate of 20 ℃/min to complete the test.

As is clear from the results in tables 3 and 4, the polymer layer 204 formed by the heating method has a higher Tm point than the polymer layer 204 formed by the kneading method, and since the Tm point of the material is related to the strength thereof, it can be seen that the polymer layer 204 in table 3 has stronger mechanical properties than the polymer layer 204 in table 4.

In addition, after the polymer layer 204 formed by kneading is heated (e.g., exceeds the Tm point) and cooled down once, it is interfered by the low molecular weight compound contained therein without having a chain entangled structure, so that the Tm point is lost, and the mechanical strength thereof is lowered. However, after the polymer layer 204 formed by heating (e.g., exceeding Tm point) and cooling, the polymer layer 204 can still maintain its structure and Tm point because the polymer layer 204 can have a chain entangled structure. For example, the polymer layer 204 can maintain its mechanical strength and Tm point even after being heated and cooled more than 30 times, so that the mat body composite structure 1 can be deformed by heating for many times for repeated use.

In some embodiments, additional localized reinforcing structures may also be provided on the fabric layer 100 and/or the support layer 200 to further enhance the mechanical properties of the mat composite structure. For example, FIG. 3A is a top view of a mat body composite structure 3A according to some embodiments of the present invention. In fig. 3A, the mat body composite structure 3A may further have a plurality of strip-shaped local reinforcement structures 400 (local reinforcement units). The local reinforcing structure 400 may be provided into the meshes of the fabric layer 100 and/or the support layer 200 by, for example, thermal compression bonding. In some embodiments, the localized reinforcing structures 400 are in direct contact with the fabric layer 100 and/or the support layer 200.

Although the local reinforcing structure 400 shown in fig. 3A has a stripe shape, the invention is not limited thereto. For example, fig. 3B is a top view of a mat body composite structure 3B according to some embodiments of the invention. In fig. 3B, the mat body composite structure 3B may also have a sheet-like local reinforcement structure 410 (local reinforcement unit) thereon. The strip-shaped local reinforcing structures 400 can reduce the amount of material used, while the sheet-shaped local reinforcing structures 410 can further enhance the mechanical strength of the mat body composite structure 3B.

Fig. 3C-3E are cross-sectional views of pad body composite structures having the localized reinforcing

structures

400 or 410 described above in some embodiments. The localized reinforcing

structures

400 or 410 may be disposed on one side near the fabric layer 100 (fig. 3C), one side near the support layer 200 (fig. 3D), or may be disposed on both sides of the mat composite (fig. 3E). It should be noted that the local reinforcing

structures

400 or 410 are disposed in the meshes of the fabric layer 100 or the support layer 200 and do not protrude from the fabric layer 100 or the support layer 200. In other words, the localized reinforcing

structures

400 or 410 may be coplanar with the fabric layer 100 or the support layer 200.

Tables 5, 6, and 7 are data of mechanical properties of the mat composite structure without the local reinforcement structure, the mat composite structure 3A with the local reinforcement structure 400, and the mat composite structure 3B with the local reinforcement structure 410, respectively.

TABLE 5 No local reinforcing Structure

TABLE 6-Placement of local reinforcing structures 400

TABLE 7-setting local reinforcing structures 410

The properties of the foregoing tables 5 through 7 were measured by the ASTM D790 standard test method. The mechanical properties (e.g., peak force, peak bending stress, modulus of curvature, cord modulus of curvature, etc.) of the pad body

composite structure

3A or 3B are enhanced with the provision of either the localized reinforcing structures 400 or the localized reinforcing structures 410 as compared to the pad body composite structure of table 5, which does not have localized reinforcing structures. Therefore, the local strength of the cushion body

composite structure

3A or 3B can be further enhanced to meet various requirements.

In some embodiments, the material of the localized reinforcing structure 400 or the localized reinforcing structure 410 may comprise a polymeric material such as polycaprolactone, polyurethane, or the like. In some embodiments, the material of the localized reinforcing

structures

400 or 410 may be the same as the material of the polymer layer 204 described above to facilitate control of the strength of the mat body

composite structure

3A or 3B. However, the present invention is not limited thereto, and the local reinforcing structure 400 or the local reinforcing structure 410 may be formed by using a material different from the polymer layer 204, depending on the design requirement.

In some embodiments, additional adhesive layers (not shown) having a mesh structure corresponding to the mesh H described above may be disposed between the fabric layer 100 and the support layer 200, and/or between the fabric layer 300 and the support layer 200. The adhesive layer may include adhesives, hot melts, and the like, including polymeric materials such as polycaprolactone, polyurethane, and the like. In some embodiments, the lamination of the fabric layer 100 and the support layer 200, and/or the fabric layer 300 and the support layer 200 may be performed by the polymer layer 204.

The mat composite structure can be deformed by heating at low temperature (such as between 65 deg.C and 70 deg.C), and has good mechanical properties at room temperature (such as about 30 deg.C), such as 10 deg.C⁸The Young's module as described above, and the fabric layer 100 compatible with the human body, can be made into a device such as a protector, an insole, etc. which is in contact with the human body and can be easily deformed by a general user as desired. For example, fig. 4A is a top view and fig. 4B is a cross-sectional view of a mat body composite 4 according to some embodiments of the present invention. It should be noted that the fabric layer 100 of the mat composite 4 does not cover the entire support layer 200, but rather exposes a portion of the upper surface 210 of the support layer 200. Therefore, as shown in fig. 4C and 4D, the pad composite structure 4 can be heated at a low temperature (e.g., between about 65 ℃ to about 70 ℃) to be deformed into a cylindrical protector (e.g., usable as a plaster), and the upper surface 210 can be disposed on the lower surface 220 of the support layer 200. After cooling (e.g., to room temperature), the upper surface 210 and the lower surface 220 can be attached to each other, and the shape of the cushion composite structure 4 can be fixed. Therefore, the cushion composite structure 4 can be easily deformed by a general user according to various requirements to adapt to different users (e.g., to fit different human shapes). In addition, the cushion composite structure 4 can be repeatedly used to saveThe cost is low, and the storage can be carried out by flattening when the storage is not used, so that the required storage space can be reduced. It should be noted that when the cushion composite structure 4 is used as a protector (e.g., a head cover, a shin protector, a neck protector, a waist band, etc.) in the manner as shown in fig. 4D, the fabric layer 100 is directed to the inside (the side directed to the human body), and since the cushion composite structure 4 has mesh holes, the air permeability and the comfort in use can be increased.

In some embodiments, the pad body composite structure can also be made into the shape of an insole, such as the insole 5 shown in fig. 5. The insole 5 may have an insole body 52 and an arch part 51 arched from the insole body 52. Since the insole 5 is formed by using the above-mentioned heat-deformable pad composite structure, the shape of the arch part 51 can be adjusted by low-temperature heating to fit various sole shapes. In addition, since the cushion composite structure has good mechanical properties at room temperature, the durability of the footwear insole 5 can be improved. In addition, since the pad body composite structure has meshes, the air permeability of the insole 5 can be increased, so that a user can feel more comfortable.

In summary, the present invention provides a cushion composite structure, and an insole and a protector using the cushion composite structure. It should be noted that the present invention is not limited thereto, and various products that need to be deformed according to the user's needs and have good mechanical properties when used at room temperature can be made from the mat body composite structure that can be deformed by heating at a low temperature and can have good mechanical properties at room temperature.
